Mukesh Arora is the General Manager at Bharat Heavy Electricals Limited (BHEL). He has been instrumental in deploying the Security Operation Centre (SOC) Solution at BHEL and achieving a consequential reduction in breaches and down time.
Given the current state in which cybersecurity threats are becoming increasingly sophisticated and complex – rendering critical infra at public sector organizations particularly vulnerable to attacks, BHEL established a state-of-the-art Security Operations Centre (SOC) to continuously monitor and improve the organization’s security posture. The SOC helps in preventing, detecting, analysing and responding to cybersecurity incidents with the aid of both technology and well-defined processes and procedures. The SOC is based around a Security Information and Event Management (SIEM) system which aggregates and correlates data from security feeds. Additionally, it collects and analyses security event data in real time for early detection of targeted attacks and data breaches. All internet traffic that enters or goes out of BHEL is monitored on a 24x7 basis. The SOC has reduced enterprise risk since it protects the business and helps the company move from a reactive response approach to proactive mitigation. Establishment of the SOC also complies with the advice of Government-appointed national nodal agencies like National Critical Information Infrastructure Protection Centre (NCIIPC) and Indian Computer Emergency Response Team (CERT-In). The solution is appliance-based and deployed in a high availability mode capable of handling 2500 Events per Sec (EPS) at normal load and 20,000 EPS at peak load. In addition to bringing peace of mind, the SOC deployment also reduced the number of cybersecurity breaches as well as the down time.
